Assessment of water quality in freshwater Chacha Kota Banswara, Rajasthan

Abstract

Ponds are known to have a higher species variety. Many aquatic creatures and plants call them home. The study aims to compare the water quality in the Chacha Kota to provide a baseline for managing and conserving this aquatic species and to help enhance the quality of water biodiversity. Chacha Kota is a small village/hamlet in Banswara Tehsil in Banswara District of Rajasthan State, India. It is a fish habitat, mostly for carp. Water samples were taken monthly from study locations from Dec 2019 to Nov 2020 during the study period. The samples were maintained per APHA's preservation protocol, and analysis was performed per established procedures. Major water parameters such as Temperature (16.35 °C to 32.45 °C.), DO (2.5 mg/l to 9.05 mg/l.), BOD (1.5 mg/l to 4.6 mg/l), Free CO2 (0.15 mg/l to 5.65 mg/l), pH value (5.65 to 8.5), Total alkalinity (87 mg/l to 255.7 mg/l), Nitrate (0.487 mg/l to 0.825 mg/l) and Phosphate (0.215 mg/l to 1.86 mg/l) were recorded. Significant correlation coefficient (r) Temperature–alkalinity (0.9115), Temperature–BOD (0.957), Temperature–Free CO2 (0.956), Temperature–Nitrate (0.943), Alkalinity–BOD (0.855) Alkalinity-Free CO2 (0.927), Alkalinity-Nitrate (0.888), BOD-Free CO2 (0.932), BOD-Nitrate (0.891), Free CO2-Nitrate (0.958) was observed between the physico-chemical parameters.
